How to retract a Git commit

When using the Git version control system, sometimes we commit code by mistake. Here's how to retract those commits:

1. Using the git reset

git reset command allows you to move the staged or the committed changes are withdrawn. To retract your last commit, use the following command:

<code>git reset HEAD^</code>

This will retract your last commit and restore the working directory to the state it was in before the commit.

2. Use the git revert

git revert command to create a new commit to undo the previous commit. To retract the most recent commit, use the following command:

<code>git revert HEAD</code>

This will create a new commit with the opposite contents of the previous commit.

3. Use the git reflog

git reflog command to display the history of all commits. You can use this to find the SHA-1 hash of the commit you want to retract. Once the hash is found, the commit can be retracted using the following command:

<code>git reset <SHA-1 哈希></code>

This will retract the specified commit and restore the working directory to the state it was in before the commit.

4. Using the interactive stage area

The interactive stage area allows you to select specific changes to undo. To use the interactive stage area, follow these steps:

• Run git reset -i HEAD
• Mark the commit you want to retract as "pick"
• Rungit commit --amend

This will create a new commit containing all the changes you selected, but excluding the ones you retracted Change.

Note:

• Only your local submission can be withdrawn. If you have pushed a commit to a remote repository, you will need to use another method to retract it.
• After retracting a commit, you may need to force push the changes to update the remote repository.
